BLOWTORCH.

Application filed May 25, 1925. Serial No. 32,707.

This invention relates to blow torches;

In blow torches as heretofore constructed, it has been the universalpractice to use gasolene and it has also been necessary to wait a fewminutes after the torch is lighted before it will give the full and hotblast required.

This invention is designed to overcome such defects, and objects of,such invention are to provide a blow torch which may be instantlylighted and will immediately give the requisite full blast of flamewithout the necessity for the initial wait, and which is so constructedthat it will use kerosene with equally good results as those obtainedfrom the use of gasolene and without the danger incident to the use ofgasolene.

Further objects are to provide a construc tion which may be readilyapplied to standard types of blow torches with a minimum of changes, orwhich may be made as a complete unit if preferred.

An embodiment of the invention is shown in the accompanying drawings, inwhich The single figure is a view of the blow torch with the majorportion in section to show the construction.

Referring to the drawings it will be seen that the usual reservoir ordrum 1 is provided and is adapted to receive the kerosene. This drumcarries an upwardly projecting pipe 2 which communicates with the lowerportion of the reservoir by means of the pipe 3. The pipe 2 isrelatively sturdy and supports a fitting l at its upper end. Thisfitting is provided'with a nozzle 5 screwed in its outer end and havingan outwardly tapered aperture. A compressed air nozzle 6 projects intothe fitting a into proximity the nozzle 5, as shown in the figure. It isconnected by means of a small tube 7 with a "alve 8 screwed into theupper end or the hollow handle 9. This valve is provided with a needlestem 10 threaded into its body and provided with a suitable manipulatingknob or handle 11, whereby the flow of air may be regulated.

The lower end of the hollow handle carries an outwardly projecting L 12to which is secured the hose receiving member 13, such member beingadapted to receive a compressed air hose from any suitable source of suply.

t is to be noted from the figure that the fitting t supports aperforated open ended burner drum 14; in spaced relation to the nozzle 5and, it desired, suitable tool receiving brackets 15 of dillerentheights may be secured to the burner drum.

In using the device, it is merely necessary to open the air valve and tolight the outwardly projected atomized stream of fuel and air. It is tobe noted that the line stream of compresed air sucks the keroseneupwardly through the pipes 52 and 3 and projects it in a blast in mistlike form through the nozzle 5. Thus, the device is ready for instantuse and prior heating is not required as in the usual types of blowtorches. Further it has been the previous practice to rely upon thevapor pressure of the gasolene in order to secure the necessary pressurefor the blast. For this reason, therefore, it has been impossible to usekerosene or other fuel or low volatility with satisfaction. However, inpractising this invention any desired fuel such as kerosene may beemployed with the utmost case.

Although the invention has been described in considerable detail, it isto be understood that the invention may be variously embodied and is,therefore, to be limited only as claimed.

I claim:

A portable blow torch having a convcutional luel receiving drum and ahollow handle carried thereby and having a pipe leading into said drumand below the fuel level, a nozzle carried by said pipe and having aforwardly projecting aperture through which fuel n'iay be sprayed, afitting screwed into the nozzle and having a tapered nozzle alining withsaid aperture and adapted to project fuel through such a erture, a pipecommunicating with the upper end of said hollow handle and leading tosaid second men tioned nozzle, a manually controlled valve interposedbetween the pipe and the hollow handle, and a fitting closing the lowerend 01" said hollow handle and having an out wardly projecting air pipereceiving neck, whereby air under pressure may be supplied through saidhollow handle to said second mentioned nozzle.

In testimony that I claim the foregoing l have hereunto set my hand atSaukville, in the county of Ozaukee, and State of Wisconsin.
